The technical scheme solving the problems of the technologies described above is:
A kind of y-type filter blowdown cleaning plant, it comprises two y-type filters, inlet pipeline, outlet pipeline, water inlet butterfly valve, water outlet butterfly valve, blowoff line, blowoff valve, the inlet pipeline of two y-type filters is connected in parallel, the outlet pipeline of two y-type filters is connected in parallel, on the inlet pipeline of two y-type filters and outlet pipeline, be separately installed with into water butterfly valve and water outlet butterfly valve, the blind flange of the installation filter screen of two y-type filters connects respectively blowoff line, and blowoff valve is installed on blowoff line.
Above-mentioned y-type filter blowdown cleaning plant, the center of the blind flange of the installation filter screen of described two y-type filters is cut with respectively circular hole, one end of circular hole welding blowoff line, blowoff line is inverted L shape, at the end of blowoff line, blowoff valve is installed.
Above-mentioned y-type filter blowdown cleaning plant, hydrops groove is installed below two y-type filters, and there is spout hole hydrops groove side, and one end butt welding of overflow pipe is on spout hole, the other end of overflow pipe causes blowdown hole, ground, and at spout hole, place is welded with screen pack.
The beneficial effects of the utility model are:
The utility model has been installed blowoff line and blowoff valve on the blind flange of y-type filter, can allow the impurity in filter more easily discharge; Two y-type filters are connected in parallel, while needing to clear up filter screen in running, can close the wherein water inlet Hand-operated butterfly valve of a y-type filter, filter screen by this y-type filter of water outlet back flushing of another y-type filter, the particle that makes to stick on screen pack is washed out, reach the object of clean filter screen, avoid changing the work of filter screen.The utility model design is ingenious, simple and practical, can to y-type filter, carry out blowdown and cleaning quickly and easily, greatly shortened maintenance time, improved the service life of cooling section heat exchanger, effectively reduce the stop frequency causing because of plugged filter accident, there is significant economic benefit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, mark is as follows: y-type filter 1, inlet pipeline 2, outlet pipeline 3, water inlet butterfly valve 4, water outlet butterfly valve 5, blind flange 6, blowoff line 7, blowoff valve 8, hydrops groove 9, screen pack 10, overflow pipe 11, ground blowdown hole 12.
The specific embodiment
The utility model is by two y-type filters 1, and inlet pipeline 2, outlet pipeline 3, water inlet butterfly valve 4, water outlet butterfly valve 5, blind flange 6, blowoff line 7, blowoff valve 8, hydrops groove 9, screen pack 10, overflow pipe 11, ground blowdown hole 12 form.
